Cheban, along with Kardashian's closest family and friends, celebrated the couple's fashion bible coup Friday afternoon. Vogue editor Anna Wintour also defended her controversial choice to place the reality TV star and rapper on the issue's cover in her Editor's Letter.

"As for the cover, my opinion is that it is both charming and touching, and it was, I should add, entirely our idea to do it; you may have read that Kanye begged me to put his fiancée on Vogue's cover. He did nothing of the sort," Wintour, also the creative director of Conde Nast, wrote.

"Kanye is an amazing performer and cultural provocateur, while Kim, through her strength of character, has created a place for herself in the glare of the world's spotlight, and it takes real guts to do that."

Gellar, for her part, has never covered Vogue. The Cruel Intentions star, who rose to fame in the '90s along with fellow teen heartthrobs Reese Witherspoon, Ryan Phillippe and husband Freddie Prinze, Jr., has fronted many other magazines in the past, including British Elle, Self, Allure, InStyle, and Seventeen.
